2005 Defender TD5

Engine just cut out, temperature gauge stopped reading (fuel gauge still reads) and fuel pump isn't running.
Turns over but won't start. Stuck at the side of the road!
Any ideas?

What does the fuel gauge read? Not to say you've run out of fuel, but it might be the pump in the tank may be on the way out. When they go bad, they can stop delivering when the tank gets low. Sometimes even at 1/2 tank.
 
Tried that no difference, l mean it could be the immobiliser but doing that hasn't fixed it.

Odd that l've got no temp gauge, could that be a clue to what's gone wrong? Fuel gauge reads okay

When you switch it on do you get the engine light? If you switch it on and depress the accelerator a few times does it initiate the purge cycle, complete with flashing engine light? If the answer is no to those questions it sounds very like mine when I had an ECU failure.
 
No purge cycle. No orange engine management light

Can't do much now as it's dark and a busy road. So not safe to stand with door open etc

Will wait for recovery and get it home then look at it tomorrow

That's if the RAC can't fix it at the roadside.

From what l have read, it sounds like the ECU might have failed.

Sounds very like the ECU fault I had in October 2016 then.

On the plus side, the firm 'ECU Testing' was able to fix it inside a week, and they even honoured their lifetime warranty when it went wrong again four years later.

I can't remember if you've got a Nanocom or some sort of fault code reader, but mine wouldn't talk to the Nanocom either - it had more or less bricked itself.

Mechanics will assure you it is the fuel pump. Chances are it isn't in my experience.
 
Just noticed

Glow plug light isn't coming on either

So to sum up. l've got no orange engine management light, no glow plug light, no temp gauge and no fuel pump operation

Battery is now flat. Probably from the hours spent with sidelights on and trying to start it. Can l charge the battery with it still connected?

l disconnected the battery and the alarm went off.
Reconnected it and it wouldn't turn off although it stopped when l turned the ignition on and off again

So it looks like the battery is staying connected

Don't know about the TD5, but my tdci has a battery disconnect procedure; ignition on (lights on dash, not to starting position), ignition off and then disconnect the earth lead from the battery within 15 seconds. (slackening the clamp in advance helps). This is so the back up (BBUS) alarm does not go off. I have a permanent lead fitted to the battery for connecting to my CTEK charger, and have been charging with the battery connected for at least the past year with no ill effects. But I have never charged with an old fashioned type charger unless the battery has been disconnected.
